A Rhino file can have a great amount of geometry and consist of different layers where you have set up different options for a particular section of your project. Here you will learn how to limit what gets exported into Prospect and how to set up design options using Rhino layers.

Geometry Filtering

If you have a large file or you only want to review a specific part of your project, select and hide any objects that you don't need to see in VR.

The Prospect plugin for Rhino exports all the geometry in the file except for those that have been hidden using the Hide command.

Named Views

You can set cameras as scenes in Prospect using Named Views (NamedView in the command line) in Rhino

Design Options

In the Prospect plugin for Rhino, objects in layers that are set to 'off' will still be exported, but they will be hidden when you first load your experience in VR. This is handy while setting up design and material options to be reviewed immersively.

In the example below, we have copied the geometry into each of the Option layers. The layers have different materials assigned to them. Toggling these layers on and off in Prospect will show you the different material choices.

Layers in Rhino

Option 1: when Prospect first loads, it matches the state of the layers in Rhino

Option 2: setting Option1 layer to off and turning Option2 on

Option 3: setting Option2 layer to off and turning Option3 on

Best practices

Below are some modeling guidelines that will improve the quality of the virtual reality experience once inside the headset.

Delete Extraneous Geometry

As you model it’s natural for geometry to be copied and pasted accidentally around the central* model. For importing into virtual reality it is best to delete any geometry that is not part of the central model.

Removing this geometry will help create a faster more stable virtual reality experience.

Layer Setup

Assigning layers, materials or colors will improve the quality of the virtual reality experience

Avoid using colors and materials that are white as that creates glare in virtual reality. Instead, go for light grey colors.

Avoid using colors that are pitch black.

Our software currently reads semi-transparent layers as if they are glass, so that you can teleport through a window or glass door quickly. Avoid making any surfaces semi-transparent that you do not want to teleport through.

Geometry

Trim any surfaces under the mesh to avoid overlapping with the mesh that represents the terrain.

*For the purposes of these guidelines, wherever “central” model is used it is referring to the primary or focal portion of the 3D model, where you would like the user to go to in virtual reality or has the design you would like to communicate.
